Demi Moore had her eyes set on daughter Rumer's good friend Zac Efron, according to Us.

Moore, 49, "tracked down" Efron, 24, at a party in Venice. A source tells the mag, "She seemed out of her mind at this party."

Those close to the G.I. Jane actress say she's been mixing pills and Red Bulls. The insider adds:

    "She's been really down, and she's surrounding herself with young people to make her feel better."


As for the night of January 16 when the 911 call was made after Demi reportedly went into convulsions, a source tells the mag, "Everyone thought she was going to die."

Moore and Ashton Kutcher split last year after six years of marriage.
